In the school I am currently working in there is a visitors toilet. You go through a door to a little lobby with a handbasin, the there's a toilet behind another lockable door. Staff use this toilet as there are just two toilets between all staff (male and female). My issue is that 6th form are also allowed to use the visitor's toilet as a 'privilege' (?) On more than one occasion I have been to use the loo only to find a 6th form boy in the lobby area. Surely this could be a serious child protection issue? I'm not sure staff and students should share the same toilet facilities. Any thoughts?
